I'd like to create an arch in FreeCAD to be used in the architecture module. In OpenSCAD it'd look like this:

Arch in OpenSCAD

Source:

rotate(270, v=[1,0,0]) {difference() {rotate_extrude(fn=500) {translate([750, 0, 0])square([400,400]);};
translate([-2000, 0, 0]) {cube([4000, 1500, 1500]);};
}};

Using the OpenSCAD module is not a solution because I'd like to use the grid snapping features and be able to edit the arch without deleting and recreating it from OpenSCAD source code (which apparently is necessary in FreeCAD).

Searching for solutions with a search engine is impossible because apparently only referring to the architecture module (= Arch) are displayed.

可以通过以下方式在架构模块中创建一个供使用的拱门

  • 在零件设计模式下创建代表拱门面的草图
  • 在 Arch 模式下创建一个结构

等效的 FreeCAD 脚本代码是：

import Part
import Sketcher
import Arch

App.newDocument("Unnamed")
App.setActiveDocument("Unnamed")
App.ActiveDocument=App.getDocument("Unnamed")
Gui.ActiveDocument=Gui.getDocument("Unnamed")
Gui.activateWorkbench("PartDesignWorkbench")
App.activeDocument().addObject('Sketcher::SketchObject','Sketch')
App.activeDocument().Sketch.Placement = App.Placement(App.Vector(0.000000,0.000000,0.000000),App.Rotation(-0.707107,0.000000,0.000000,-0.707107))
#Gui.activeDocument().activeView().setCamera('#Inventor V2.1 ascii \n OrthographicCamera {\n viewportMapping ADJUST_CAMERA\n  position 0 -87 0 \n  orientation -1 0 0  4.712389\n  nearDistance -112.88701\n  farDistance 287.28702\n  aspectRatio 1\n  focalDistance 87\n  height 143.52005\n\n}')
Gui.activeDocument().setEdit('Sketch')
App.ActiveDocument.Sketch.addGeometry(Part.ArcOfCircle(Part.Circle(App.Vector(0.000000,-0.000000,0),App.Vector(0,0,1),200.000000),0.000000,3.141593))
App.ActiveDocument.Sketch.addConstraint(Sketcher.Constraint('Coincident',0,3,-1,1)) 
App.ActiveDocument.Sketch.addGeometry(Part.ArcOfCircle(Part.Circle(App.Vector(0.000000,-0.000000,0),App.Vector(0,0,1),300.000000),0.000000,3.141593))
App.ActiveDocument.Sketch.addConstraint(Sketcher.Constraint('Coincident',1,3,-1,1)) 
App.ActiveDocument.Sketch.addConstraint(Sketcher.Constraint('PointOnObject',1,2,-1)) 
App.ActiveDocument.Sketch.addConstraint(Sketcher.Constraint('PointOnObject',1,1,-1)) 
App.ActiveDocument.Sketch.addGeometry(Part.Line(App.Vector(-300.000000,-0.000000,0),App.Vector(-200.000000,-0.000000,0)))
App.ActiveDocument.Sketch.addConstraint(Sketcher.Constraint('Coincident',2,1,1,2)) 
App.ActiveDocument.Sketch.addConstraint(Sketcher.Constraint('Coincident',2,2,0,2)) 
App.ActiveDocument.Sketch.addConstraint(Sketcher.Constraint('Horizontal',2)) 
App.ActiveDocument.Sketch.addGeometry(Part.Line(App.Vector(200.000000,-0.000000,0),App.Vector(300.000000,-0.000000,0)))
App.ActiveDocument.Sketch.addConstraint(Sketcher.Constraint('Coincident',3,1,0,1)) 
App.ActiveDocument.Sketch.addConstraint(Sketcher.Constraint('Coincident',3,2,1,1)) 
App.ActiveDocument.Sketch.addConstraint(Sketcher.Constraint('Horizontal',3)) 
Gui.activeDocument().resetEdit()
App.ActiveDocument.recompute()
Gui.activateWorkbench("ArchWorkbench")
Gui.activeDocument().activeView().viewAxometric()
Arch.makeStructure(FreeCAD.ActiveDocument.Sketch)
FreeCAD.getDocument("Unnamed").getObject("Structure").Height = '100 mm'
Gui.SendMsgToActiveView("ViewFit")
App.ActiveDocument.recompute()
Gui.SendMsgToActiveView("ViewFit")
